23S08-1DCG

Overview

The Renesas Electronics Corporation 23S08-1DCG is a 3.3V Zero Delay Clock Multiplier designed for high-speed clock distribution and multiplication applications. Operating within a frequency range of 10 MHz to 133 MHz, this device utilizes a Phase-Lock Loop (PLL) architecture to achieve zero delay by aligning the phase between the incoming clock and output clocks. It features one LVCMOS input and eight LVCMOS outputs organized into two banks of four. The component supports spread spectrum inputs and offers low jitter performance with a maximum cycle-to-cycle jitter of 200 ps and output skew under 200 ps. It is housed in a 16-pin SOIC package.

Feature Summary

• Zero Delay PLL Architecture: Aligns output phase with input clock for frequencies from 10 MHz to 133 MHz.
• Spread Spectrum Compatible: Accepts spread spectrum input signals to reduce EMI.
• Low Jitter Performance: Specifies maximum cycle-to-cycle jitter of 200 ps and output skew of 200 ps.
• Dual Output Banks: Distributes one input to two independent banks of four LVCMOS outputs each.

Applications

• High-speed clock distribution systems requiring precise phase alignment.
• Data communication equipment operating at frequencies up to 133 MHz.
• Systems utilizing spread spectrum clocking for electromagnetic interference reduction.

Procurement Notes

Verify the specific suffix 'DCG' corresponds to the SOIC-16 package variant when sourcing. Confirm that the multiplier/divide value is set to 1x as indicated by the '-1' designation. Ensure compatibility with 3.3V core voltage requirements and check for lead-free status if RoHS compliance is mandatory for the assembly process.

Selection Notes

Select the 23S08-1DCG when a single-frequency multiplication factor (1x) is required alongside zero-delay synchronization. Compare against the -2H or -5H variants if higher drive strength or different multiplication factors (2x, 4x) are needed. Verify that the SOIC package dimensions (9.9 x 3.9 x 1.5 mm) fit the PCB layout constraints compared to TSSOP alternatives.

Part Context

This component belongs to the IDT/Renesas 2308 family of zero-delay clock multipliers. The family includes variants with different multiplication ratios (1x, 2x, 4x) and drive strengths. The 23S08-1DCG specifically denotes the 1x multiplication version in a SOIC package, distinct from the TSSOP packaged 23S08-1HPGG or high-drive versions like 23S08-2HDCG.

Replacement Considerations

For equivalent functionality, consider the 23S08-2HDCG if 2x multiplication is acceptable, or the 2308B-1HDCG for industrial temperature range variations. Direct pin-compatible replacements within the same package type should be verified against the specific multiply/divide value requirements.
